Hi,
I want to model a simple mass diffusion process, but with a concentration dependent diffusion coefficient.
In variable I defined a function for diffusion coefficient. but when I want to solve the problem it end with error ("Failed to find consistent initial values. Last time step is not converged.").
Is there any solution for this problem?
Thanks.
Saeed.
